Answer:
x ≈ 21.7 units
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos37° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{17.3}{x}[/tex] ( multiply both sides by x )
x × cos37° = 17.3 ( divide both sides by cos37°
x = [tex]\frac{17.3}{cos37}[/tex] ≈ 21.7 units ( to the nearest tenth )
